BootBandit: A macOS bootloader attack
Engineering Reports, Volume 1, Issue 1, August 2019., 2019 Historically, the boot phase on personal computers left systems in a relatively vulnerable state. Because traditional antivirus software runs within the operating system, the boot environment is difficult to protect from malware. Examples of attacks against bootloaders include so‐called “evil maid” attacks, in which an intruder physically obtains a ...

Construction of a New Biometric‐Based Key Derivation Function and Its Application
Security and Communication Networks, Volume 2018, Issue 1, 2018., 2018 Biometric data is user‐identifiable and therefore methods to use biometrics for authentication have been widely researched. Biometric cryptosystems allow for a user to derive a cryptographic key from noisy biometric data and perform a cryptographic task for authentication or encryption. The fuzzy extractor is known as a prominent biometric cryptosystem.

RiffleScrambler - a memory-hard password storing function
, 2018 We introduce RiffleScrambler: a new family of directed acyclic graphs and a corresponding data-independent memory hard function with password independent memory access. We prove its memory hardness in the random oracle model. RiffleScrambler is similar

Adding security and privacy to genomic information representation [PDF]
, 2019 Provision of security and privacy to genomic data is a key issue in current genomic information representation. Existing formats do not give a solution to these issues (or they provide a partial one), so new solutions are demanded. MPEG-G (ISO/IEC 23092,
